R for cats and cat lovers

Following the lead of JavaScript for Cats by Maxwell Ogden, Scott Chamberlain and Carson Sievert wrote R for Cats. It's a playful introduction to R intended for those who have little to no programming experience.

The bulk of it so far is a primer on data structures, and there's a little bit on functions and some dos and don'ts. It's stuff you should know before you get into more advanced tutorials.
